You were posted at a PHC catering to a population of 1,20,000. In the year 2006, a total number of 2500 liver born babies were delivered. Number of children dying under one year of age during 2006 was 150. What is the infant mortality rate of this population ?

**Core Concept**
The infant mortality rate (IMR) is a crucial indicator of a population's health status, reflecting the number of infants dying under one year of age per 1000 live births.

**Why the Correct Answer is Right**
To calculate IMR, we use the formula: IMR (per 1000) = (Number of deaths under 1 year of age / Number of live births) x 1000. In this case, the number of live births is 2500, and the number of deaths under 1 year of age is 150. Substituting these values into the formula, we get: IMR = (150 / 2500) x 1000 = 60.

**Clinical Pearl / High-Yield Fact**
IMR is a key indicator of a population's access to healthcare, sanitation, and nutrition. A high IMR can indicate a range of underlying issues, including poverty, lack of access to healthcare, and inadequate maternal and child healthcare services.

**Correct Answer:** 60.
